How did language evolve? The answer depends on what your theory of language says about language. In this talk we will look at Chomsky's latest theory of language, and at Berwick and Chomsky's account of how language, as characterised by Chomsky's theory, evolved. The guiding question will be this: "Does Berwick and Chomsky's account adequately explain how language, as characterised by Chomsky's theory, evolved?" I will argue for a negative answer.'
